y scholars country on this subject for several years of research, DFC and DTC proposed research model, pleted the prehensive analysis and parison of the single series of crane design standards and design objectives of the cost of prehensive evaluation system. But the data accumulated amount is less, less practical scope. Can be seen from the above, the design of the product cost reduction has also been a long time to stay in the local phase of the analysis and calculation, has not yet put it into the design process through the integration of CAD system, and did not introduce the concept of product life cycle , resulting in mostly qualitative analysis, quantitative analysis is based on a small number of limited data, based on statistical analysis, Therefore, the establishment of the whole process designed especially to support the initial design phase of the program and the cost of the overall structure of the information model has been the key to achieving lowcost design and the urgent need to address the problem. Innovative design of the Rapid Response 大連 科技 學(xué)院 2020 屆本科生畢業(yè)設(shè)計(論文)外文翻譯 5 Tokyo International Conference in 1992 formally proposed concurrent engineering technology, developed as the basis to reduce the design period of rapid design techniques (RDT), Current international design in parallel for rapid design, rapid prototyping, serialization modular technology and the development of virtual manufacturing technologies are relatively fast, but crane industry has not been largescale popularization and application. Simulation and Virtual Design Study abroad are more active, the simulation of mechanical product design modeling, including the current most widely used finite element method (FEM), finite difference method. Simulation technology is increasingly widely used, so that it can overe the physical space and time constraints. Digital prototype simulation designed crane products on large and plex program evaluation。 From design, engineering, production, installation, missioning and operation of the whole process of information management。 (6) The design and the corresponding highspeed crane antisway, accurate alignment of the technology。 (3) Diversity and low cost to meet market requirements with new technologies, new crane series features modular design。 (11) Large single plex product design and dynamic simulation of virtual realization。 The United States set up the Planning Board Japan also attaches great importance to the development of design technology will be designed as a technical, economic, aesthetic, and the overall integration of ergonomics, and strongly promote and adopt new technologies. In short, the economic and technical design of the developed countries and a lot more attention to innovative design, making the mechanical and electrical products, including lifting the product design, safety and reliability, technical and economic aspects of such rapid changes occur more and more design increasing levels. The development of China’s crane design has gone through a tortuous process. More than before the design is based on imitation of the Soviet Union mainly, with the designer’s experience, a great product design limitations. From the 60’s, started a new product development and design of new ponents and experimental research, to make the design experience from design imitation and gradually to experimental research and analysis phase. To 80 years, BaoGang and some very large panies with foreign crane and with the introduction of foreign joint design, manufacturing, and other forms of domestic adoption, begin in the country to introduce a number of international advanced technology and design. The same time, puter application technology into design, design work on the crane played an important role in promoting development. However, our crane design are still many problems, primarily the design of most small and medium analysis is not enough, low capital investment, personnel training, keep up with development needs, has not formed to develop new products or old products, design and ability to cope with the introduction of advanced technologies and products, not from a design perspective digestion, and no ability to reinnovation. Designers do not form a reasonable echelon。起重機市場近年來也異常的活躍起來,這無疑給起重機的設(shè)計帶來了更高層次的發(fā)展要求,起重機的創(chuàng)新設(shè)計已經(jīng)成為各企業(yè)提升競爭能力的最主要手段和途徑。同時高度綜合也是現(xiàn)代起重機設(shè)計的顯著趨勢。 我國起重機設(shè)計的發(fā)展經(jīng)歷了一個曲折的過程。這些企業(yè)已大量采用新的計算機新技術(shù) ,二維 CAD 早已普及,三維設(shè)計已推廣。從上述可看出,對產(chǎn)品降低成本的設(shè)計長期以來還一直停留在局部階段的分析和計算,尚未把它納入到貫穿設(shè)計全過程一體化的 CAD 系統(tǒng)中,且未引入產(chǎn)品的全壽命周期概念,導(dǎo)致分析結(jié)果大多是定性的,少數(shù)定量分析又是基于有限數(shù)據(jù)的統(tǒng)計分析基礎(chǔ)上的,因此,建立支持設(shè)計全過程尤其是初始方案和總體結(jié)構(gòu)設(shè)計階段的成本信
